Whole Genome Sequence of an Edible Mushroom Stropharia rugosoannulata (Daqiugaigu)

mycolabadmin

Scientists have decoded the complete genetic blueprint of the wine cap mushroom (Stropharia rugosoannulata), a popular edible mushroom grown worldwide. The research identified over 12,000 genes and discovered the mushroom contains powerful enzymes that break down plant material, explaining why it grows so well on straw and corn stalks. The study also revealed that different parts of the mushroom (cap and stem) have different functions, with stems focusing on energy production and caps on growth and development.

Growth Propagation of Liquid Spawn on Non-Woven Hemp Mats to Inform Digital Biofabrication of Mycelium-Based Composites

mycolabadmin

Researchers developed a method to grow mushroom mycelium (fungal threads) in liquid form and apply it to hemp mats to create sustainable building materials. By testing different growth conditions and concentrations, they found ways to control how fast the mycelium spreads and covers the surface. This liquid-based approach offers advantages over traditional methods because it allows for more precise application and better control of material properties.

Genome Sequencing of Cladobotryum protrusum Provides Insights into the Evolution and Pathogenic Mechanisms of the Cobweb Disease Pathogen on Cultivated Mushroom

mycolabadmin

Researchers sequenced the complete genome of Cladobotryum protrusum, a fungus that causes cobweb disease on cultivated mushrooms. This genome contains genes for producing toxins and enzymes that help the fungus attack and digest mushroom cells. Understanding this genetic blueprint could help farmers develop better strategies to control this disease and protect their mushroom crops from significant economic losses.

Uncovering the transcriptional landscape of Fomes fomentarius during fungal-based material production through gene co-expression network analysis

mycolabadmin

Scientists studied how the mushroom Fomes fomentarius decomposes plant materials and grows as a biomaterial for making sustainable products. Using advanced gene analysis, they discovered which genes control the fungus’s ability to break down wood and form composites, and identified key genetic switches that could be used to improve material production. This research provides a blueprint for engineering better fungal-based alternatives to conventional construction and packaging materials.

Impact of bottom ash addition on Pleurotus ostreatus cultivation on coffee ground substrate

mycolabadmin

This study investigated growing oyster mushrooms on a mixture of used coffee grounds and coal plant bottom ash. The researchers found that adding small amounts of bottom ash (1-5%) slowed mushroom growth slightly but actually reduced harmful heavy metals in the final mushrooms compared to using only coffee grounds. The leftover substrate after mushroom harvest could be used as a fertilizer for poor soils, creating a complete recycling system that turns industrial and food waste into useful products.

Transcriptome Analysis Reveals Critical Genes Involved in the Response of Stropharia rugosoannulata to High Temperature and Drought Stress

mycolabadmin

This study examined how a type of edible mushroom called Stropharia rugosoannulata responds to high heat and dry conditions by analyzing which genes become active. Researchers found that under stress, the mushroom activates specific genes that help it survive, particularly through a cellular communication pathway called MAPK. They identified 15 key genes that could be useful for breeding mushroom varieties that better withstand harsh growing conditions, which could improve mushroom farming efficiency.

The Fungus Among Us: Innovations and Applications of Mycelium-Based Composites

mycolabadmin

Mycelium-based composites are eco-friendly building materials made by growing mushroom fungus on agricultural waste like sawdust and straw. These materials are lightweight, provide excellent insulation and soundproofing, and are much more sustainable than synthetic alternatives. However, they absorb water easily and aren’t strong enough for load-bearing structures, making them best suited for insulation and non-structural panels.

Use of Pleurotus ostreatus to Enhance the Oxidative Stability of Pork Patties during Storage and In Vitro Gastrointestinal Digestion

mycolabadmin

Oyster mushrooms can be added to pork patties to keep them fresh longer by preventing fat and protein damage during storage. The mushroom powder works similarly to synthetic antioxidants but is completely natural. When eaten, the beneficial compounds from the mushroom survive digestion and may provide health benefits to consumers.

Growth Phase-Dependent Changes in the Carbohydrate Metabolism of Penicillium Strains from Diverse Temperature Classes in Response to Cold Stress

mycolabadmin

This study examined how different fungal strains from cold and warm environments respond to sudden temperature drops. Researchers tracked enzyme activity related to energy production and found that fungi adapted to cold environments handle stress better than warmth-loving fungi. The type of enzyme activity and how old the fungal cells were both affected the response to cold, providing insights that could help predict how disease-causing fungi behave in cold conditions.

Experimental Assessment of Multiple Properties of Mycelium-Based Composites with Sewage Sludge and Bagasse

mycolabadmin

Researchers created building materials using mushroom mycelium grown on sewage sludge and bagasse, eliminating waste while producing lightweight, eco-friendly composites. These materials showed excellent strength and thermal properties comparable to conventional highway backfill materials, but with significantly lower environmental impact. The study demonstrates that mycelium can effectively bind sewage sludge into useful construction materials, offering a practical solution for waste management and sustainable building.
